Every time I have to generate reports and I update Gibbon I have to add a couple of lines of code to the MpdfRenderer.pdf in order to get Korean text to show properly (not as missing symbol glyphs). I don’t know if this affects anyone else, or if it’s specific to Korean, but it might be nice to have this as either the default option or a checkbox in the report configuration.
These are the three lines that I add to MpdfRendered (line 219, after the $config block):
$config['autoLangToFont'] = true;
$config['autoScriptToLang'] = true;
$config['useAdobeCJK'] = false;
